I tried using
/string1\|string2
didn't work.
Tried
/string1|string2
didn't work.
Any help?
You have to put the 'alternations' inside a 'grouping' of \(...\). This should work:
/\(string1\|string2\)
To search for foo or bar you can do this:
/[fb][oa][or]
but that's not very scalable :)
Solaris 10 native vi(1) doesn't support regex alternation. See BREs (basic regular expressions) in regex(5) (man -s5 regex).
Solaris 11 ships with vim.

According to this page you can use perl compatible regular expression with
:perldo s/pattern/insert/g.
This works fine.
But, how can I get interactive search and replace with PCRE syntax in vim?
Since this does not work with perldo I search for a different solution.
Till the current release version of vim, there is no way to do :s/[perlRegex]/bar/c
So you are asking for a feature that doesn't exist.
You can do matching with verymagic, however it is not Perl Regex compatible flag. It is still using the vimregex engine, just changed the way of escaping regex patterns.
For example, in perl, you can do lookahead/behind (?<=foo)..., (?=foo), (?!foo).., you can use the handy \K : som.*ing\Kwhatever etc, you cannot use those syntax in vim directly, no matter which 'magic' level you have set. Vim has the same feature, but different syntax:
\#=
\#!
\#<=
and also the \zs \ze are very handy, even more powerful than perl's \K.
Vim is an Editor, with vim regex, you can not only do text matching, but also match base on visual selection, cursor position and so on.
If you really need to do complex pattern matching and really need do them in vim, learn vim regex! It is not difficult for you if you "know pcre very well"
Probably the closest you can get is:
:s/\vfoo/bar/gc
I suggest to try eregex plugin. It maps perl compatible regular expressions to VIM regex syntax.
In your example, s/pattern/insert/g is a perl command, not a Vim command using a perl-compatible regular expression syntax.
If perl doesn't have an equivalent of Vim's /c flag you will need to find an alternate method like… writing an actual perl script.
So I started learning Scala today and I got all my vim config files working for Scala syntax highlighting and such, but the files I downloaded (http://lorenzod8n.wordpress.com/2008/01/11/getting-scala-syntax-hightlighting-to-work-in-vim/) did not seem to include the apparent Scala convention of indent by 2 spaces.
Since for my job I mostly work in C++ and Python, I currently have my set tabstop=4.
I've been trying to figure out how to use the if/endif statements for .vimrc files to do set tabstop=2 if the extension if *.scala, otherwise use tabstop=4 but not having much luck.. help?
Thanks!

When I have something like s#hello#bye#; in my Perl script vim's syntax highlighting is messed up after that line. It only works correctly if I use / as the delimiter, as in s/hello/bye/;. Does anyone know if/how I can fix this?
Thanks a lot in advance for your replies.
My Debian packaged vim 7.1 highlights OK with s#foo#bar#g. The Debian package does not contain vim's perl-specific features.
Also, no problem with RHEL vim 7.0 which has perl features enabled.
I remember seeing this problem with syntax highlighing some time back, so it might be your vim version and/or perl syntax highlighting rules.
"The only thing that can parse Perl is perl."
But seriously, Perl has a massively irregular grammar and it's not surprising that it confuses some syntax highlighters. The most successful one I've seen is CPerl mode for Emacs. But I guess that's not particularly useful for a Vim user.
Most PHP Developers are likely familar with the Syntax Highlighter called "GeSHi", which takes code, highlights it, with the use of HTML and CSS:
include('geshi.php');
$source = 'echo "hello, world!";
$language = 'php';
$path = 'geshi/';
$geshi = new GeSHi($source, $language, $path);
echo $geshi->parse_code();
GeSHi Supports a wide range of languages.
I wonder, is there a similar Module for Perl?
Perl has a port of Kate highlighting system: Syntax::Highlight::Engine::Kate which seems to be somewhat close to what you need. It appears to be part of Padre.
You also have an option of HTML client side highlighters (logic is obviously JS), such as Google's code prettifyer
Two good lists of syntax highlighting engines are:
Wiki syntax highlighting article - among the ones it lists, the Perl ports/APIs seem to exist for Kate and Colorer (Syntax::Highlight::Universal)
This very good review of HTML syntax highlighters, which contains a lot of client-side ones such as SHJS and many others.
Please be aware that NONE of those generic highlighters work "100% correctly", the way the syntax highlighters work in good IDEs, because they use regular expressions for approximate parsing instead of lexers for actual language grammar parsing. More details on the Wiki
You can also consider this for client side syntax highlighting.

I have had some very good results with the PPI::HTML package. It uses PPI to parse the Perl before converting the text to HTML.
Pure Perl: Syntax::Highlight::Engine::Kate (there is Kate plugin for Padre IDE).
Wrappers for C libraries: Syntax::Highlight::Universal, Syntax::SourceHighlight.
Using external tools: Text::VimColor, Text::EmacsColor.
Also there are many one-language highlighters on CPAN.
You can always write a small php script to make GeSHi usable from command line and then call it within your perl script.
I did this for gitweb so I could leave svn (and websvn) behind for good.
My search brought me here, because I was looking for a 'Perl Syntax Highlighter' like the title said and not an general highlighter implemented in Perl.
To highlight only Perl, perltidy --html can be used. It belongs to the Perl::Tidy distribution the main module can be imported and used without spawning a process.

So not what the OP actually wanted to know, but hopefully of help for others coming here for the same reasons like me ... :)
When I run Emacs command ispell-buffer on an Emacs buffer which is in the LaTeX mode, ispell checks spelling also inside math expressions.
I'd very much like to disable this. Is there an easy way to do it?
I've read about detex but detex does not seem to be integrated into Emacs.
It shouldn't do this, if you are using latexisms (eg. \[ ... \], equation environments, &c) to invoke math mode. Check the contents of ispell-tex-skip-alists; cf. section 6 of the ispell FAQ for what kind of thing should be there.
You can use $..$, $$..$$ to mark out maths using ispell-tex-skip-alists, but beware getting them out of kilter...
Postscript
Check also the value of the ispell-parser variable: this should be 'tex, otherwise ispell will not look for $...$ and $$...$$ regions.
Yes, you can: install aspell instead of ispell, and use flyspell with it.
This doesn't answer your question directly, but I have found Flyspell, an on-the-fly spell checker, incredibly useful when editing LaTeX documents. It still spellchecks inside equations, but it is much easier to ignore a few extra red underlines than ispell's interactive commands.
You may know this, but you can press A during spell checking to add a word to the buffer-local dictionary (that's capital A, lowercase a adds it to the global dictionary). It's not ideal, but this is how I usually suppress spell-checking of technical terms and variable names, etc., in my LaTeX documents.
This AUCTeX mailing list thread : "spell checker (ispell-buffer) complains about products in math modes" has some workarounds and the answer demonstrates how to use ispell-tex-skip-alists.
Another approach is to use ispell-skip-region-alist. The following example is to exclude org-mode src blocks:
(add-to-list 'ispell-skip-region-alist '("#\\+begin_src". "#\\+end_src"))
